UpdateProjectConfig

Last Updated：2026-01-20 07:59:22 Updated

This topic describes the OpenAPI provided by OceanBase Migration Service (OMS): UpdateProjectConfig.

Purpose

This API is used to update the parameters of a data migration or synchronization task.

Call description

The interface uses full replacement for updates:

Full coverage: When you call this interface, you must pass a complete set of configuration information.
Unsent means deleted: In the new configuration set, task configuration items not included will be deleted.
Differential update: Only configuration items inconsistent with the current system records will be updated to the new ones you provided.

Limitations

This interface applies to OMS V4.2.4 and later.
